I.F.

The best aspect of collaborating with my spouse is sharing the enjoyment
of doing research. It is an enormous "pro". We have the same passion
for math, and it is incredibly rewarding to share it.
It is also practical: there are plenty of opportunities to discuss mathematics.
The best aspects of the relationship, the reasons why I am in this
relationship, surface in the collaboration.

The worst aspects of the relationship, the things I dislike the most,
also surface in the collaboration. It is, sometimes, too much
surfacing. One could try to minimize this by separating what is
personal from what is not. Sometimes it helps me to put myself in a
professional mode.

In my personal experience our collaboration suffered when there was a
problem with our family. If I had been collaborating with somebody
else, there would have been more chance to keep going because the
friendly pressure of an outsider might have helped.
